IMPROVEMENT IN IIARROWS.`

'ro ALL WHOM 1T MAY coNcERM Be it known that I, LEMUEL BECK-ELSHYMER, of Leavenworth, in the county of Leavenworth, and State of Kansas, have invented a new and useful Improvement in Harrows; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-` l Figure 1 is a front view of my improved machine.

Figure 2 is a sectional View of the same, taken through the line :1: rv, tig. l.

Figure 3 is a detail view representing the harrow-shoe when made in one piece.

' Figure is a detail cross-section of 'the same, taken through the line y y, fig. 3f

Similar letters of reference indicate like parts. e My invention relates to harrows 4mounted upon wheels and receiving a reciprocating transverse movement from the saidwheels by the interposition of gearing; and it consists in the barrow-shoes, to which the teeth are attached, in combination with the levers, connecting-hars, and crank-wheel, by` which motion is communicated from the gearing to said barrow-shoes; and in the lever, in combination with the stationary and movable. frames of the machine, the whole being constructed and arranged as hereinafter more fully described.

I A are the wheels and B is the axle ofthe machine. C is a frame securely attached to the axle B and tongue 'D of the machine, `and upon which the drivers seat E rests. F is a frame which rests upon th'e top of the frame C, and the side bars of which are pivoted or hinged to the rear ends of thevside bars of the frame C in such a way 4that the forward end of the said frame E may be raised to lift the harrow-teeth out of the ground, and -that the said frame F may be moved backward and forward to throw the machine out of and linto gear. G is a.'4 lever, the lower end of which is swivelled to the tongue D or stationary frame C, and its middle part is connected with the frame F by a swivel, through theeye of which passes the guide-rod H, `the ends of which are bent at right angles and secured to the forward cross-bar of the said frame F. By this construction, by' means of the single lever Gr the machine may beV thrown out of and into gear, and the barrow raised from or lowered to the ground, as desired. I are vertical frames securely attached to the frame F, so that by the raising or lowering of the said frame F the frames I will be carried with them. The frames I'are strengthenedhy, strong inclined braces J, as shown in the drawings. `The lower cross-bar of the frames I forms slides z for the harrowshoe or shoes K or K to slideback and forth upon. The sides of the feet z'should be plated to prevent wear and diminish friction, as shown in tig. 2. K K are the shoes, to which the harrow-teeth c are securely attached, and which lit upon the feet z' of the frames I, being kept in place by lthe keepers k2, attached to the said shoes, and projecting over the upper side of the feet, as shown in g. 2. The shoes K may be made in two parts, as shown in fig. 1, or in one piece, as shown in fig. 3. To the rear side of the shoe K or shoesK, near their outer ends, are pivoted the ends of the connecting-bars L, the other ends of which are' pivoted to the lower ends of levers M. The levers M are pivoted` to the central cross-bars of the frames I, and to their upper ends` are pivoted the ends of the connecting-bars N, the other ends of which are pivoted to'the crank-pin of the orank-wheel O. The crank-wheel O is attached to the end of the shaft P, which revolves in hearings in the frame F, and to the rear endl of which is attached a bevel gear-wheel, R, the teeth of which mesh into thel teeth of the bevel geapwheel S, attached to the shaft T. The shaft T revolves in bearings at the rear end of the frame F, and has gear-wheels'U attached to its ends, the teeth of which mesh into the teeth of the large gear-wheels V, securely att-ached to the wheels A so as to be carried with the said wheels A intheir revolution, so that by the revolution of the wheels A in drawing thc machine forward a reciprocating transverse movement is given to-the barrow-teeth, while at the lsame time they are being drawn forward through the ground.

Having thus described my invention, what I claim as new, and desire to secure hy Letters Patent, i's

l. The barrow-shoes K or K, to which the teeth k1 are attached, in combination with the connecting-bars 'L, levers M,'connectingbars N, and crank-'wheel O, by which motion is communicated from the gearing to the said shoes or shoe, substantially as herein shown and described.

2. The combination of the lever G with the stationary frame C or tongue D, and with the movable frame F, substantially iu the manner herein shown and described and for the purposesset forth.
